Geothermal Probe with Heat Pump Principle Teaching Equipment

Geothermal Probe with Heat Pipe Principle is designed for practical demonstration and investigation of the operation of a geothermal probe based on the heat pipe principle. The system features a glass heat pipe with a transparent temperature-control jacket for direct observation of the heat transfer process.

Water is used as the working medium for heat dissipation in the heat exchanger. The working medium can be supplied through the laboratory water network or a water chiller to maintain a maximum water temperature of 16 °C.

The setup includes a U-tube geothermal probe made of copper, heating circuits, pumps, a water tank and sand container for practical investigation of geothermal heat transfer. The system also allows simulation of the energy balance of a heat pump.

Temperature and flow rate can be measured during experiments, while PC-based software supports data acquisition via USB and analysis of experimental results.

Designed and manufactured by Atico Export to meet the practical requirements of modern technical education laboratories.
